Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reading electronic identification documents are time-consuming and insecure, particularly in long-range radio communication where data can be easily intercepted, and existing secure protocols are cumbersome and slow.
Innovation Solution
A method that uses a long-range radio link for transmitting encrypted identification data and a short-range radio link for securely transmitting the data key, ensuring fast and secure reading by separating data and key memory interfaces and using authentication processes in accordance with BSI TR-03110 protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If encrypted identification data is transmitted via long-range radio link, then reading speed is improved, but security deteriorates due to easy data interception
Solution Approach 1:
The patent segments the identification document into two separate memory components: data memory for storing encrypted identification data and key memory for storing the data key. This allows data to be transmitted via long-range radio link for speed while the key is transmitted via short-range radio link for security, resolving the contradiction between reading speed and security.
2Reliability
If data key is transmitted via short-range radio link, then security is improved, but reading time increases due to additional transmission step
Solution Approach 1:
The patent performs preliminary action by having the terminal authenticate with the identification document and establish secure communication channels before data transmission. The data key is transmitted via short-range radio link only after authentication, and the terminal is pre-configured to decrypt data using this key, thereby minimizing the time loss from the additional security step.
3Reliability
If authentication processes are performed according to BSI TR-03110 protocols, then security is improved, but complexity increases
Solution Approach 1:
The patent uses the terminal as an intermediary that handles the complex authentication processes according to BSI TR-03110 protocols. The terminal performs mutual authentication with the identification document, establishes secure communication channels, and manages key transmission, thereby implementing strong security without requiring the identification document itself to be complex.

AI summary
The invention provides a method for reading an electronic identification document in a contactless manner by means of a terminal, wherein in a data reading step, encrypted identification data are transmitted from a data memory to the terminal, and in a key reading step, the data key, which is used for decrypting the identification data, is transmitted to the terminal, and in the terminal, the identification data are decrypted using the data key. The data reading step is carried out using a long-range radio connection, and the key reading step is carried out using a short-range radio connection.
